BACKGROUND OF THE INVENTION

1. Field of the Invention

The instant disclosure relates to a nebulizer and a medicine accommodating structure thereof, and more particularly to a portable ultrasonic nebulizer and a medicine accommodating structure thereof.

2. Description of Related Art

The atomization method is often used to treat respiratory diseases. The method can be achieved by using a nebulizer, and particles sprayed by the nebulizer are droplets that are about 3-5 μm. For example, liquid medicaments can reach bronchus and lungs for therapy. The procedure typically involves aerosolized particles from liquid medicament are inhaled by the mouth and nose to enter the bronchus, and the particles then are spread to the whole alveolus so that liquid medicament can be sufficiently absorbed by the human body. This way is better than oral administration. Currently, the atomization way adapted by nebulizers usually includes pneumatic atomization, ultrasonic atomization or electronic aerosol technology (e.g., piezoelectric nozzle method) for the operating mechanism of the nebulizer.

First, referring to FIG. 6 and FIG. 9, FIG. 8 shows a cross-sectional view taken along the section line B-B of FIG. 7. The medicine accommodating unit 41 is disposed in the receiving space 110. For example, the medicine accommodating unit 41 includes a main body 411, at least one auxiliary portion 412 adjacent to the main body 411, a medicine accommodating space 413 (such as a cartridge accommodation space) surrounded by the main body 411 and the at least one auxiliary portion 412, a first opening 414 formed between one of two opposite ends of the main body 411 and one of two opposite ends of the at least one auxiliary portion 412, a second opening 415 formed between the other end of the main body 411 and the other end of the at least one auxiliary portion 412, and a reinforcement rib 416 connected (or integrally connected) to an outer surface 4110 of the main body 411.

The third protection unit 53 includes a third protection body 531 extended backward from a top side of the first protection body 511 and connected between the two second protection bodies 521 and an elastic body 532 connected with the third protection body 531. The third protection body 53 is disposed on the top cover 12. One portion of the elastic body 532 is received in the exhaust vent 120 of the top cover 12 for enclosing the exhaust vent 120 of the top cover 12. The fourth protection unit 54 includes a fourth protection body 541 extended forward from a front side of the first protection body 511. The nozzle 13 is covered by the fourth protection body 541 for protecting the nebulization structure 2. In other words, the protection structure 5 includes a plurality of protection units. One of the protection units (such as the fourth protection unit 54) has a protection body (such as the fourth protection body 541) and an elastic body 532 connected with the protection body, in which the protection body is disposed on the top cover 12, and one portion of the elastic body 532 is received inside the exhaust vent 120 of the top cover 12 for enclosing the exhaust vent 120 of the top cover 12. Thus, the protection structure 5 can prevent both the power push button 31 and the at least one switching push button 32 from being touched by any foreign body, and also can prevent the medicinal liquid M received inside the receiving space 110 from leaking out of the exhaust vent 120 of the top cover 12.

The receiving hole 5310 has a first receiving portion 53101 connected to an outer surface 5311 of the third protection body 531 and a second receiving portion 53102 connected to an inner surface 5312 of the third protection body 531. The second receiving portion 53102 is in fluid communication with the first receiving portion 53101. The width W2 of the second receiving portion 53102 is larger than the width W1 of the first receiving portion 53101. The elastic body 532 has a first elastic portion 5321 received in the first receiving portion 53101, a second elastic portion 5322 connected with the first elastic portion 5321, and a third elastic portion 5323 extended downward from the second elastic portion 5322.
